The Disadvantages

Spalling of automotive bumper during paint removal.

 
  • If the substrate can be damaged by the gas generation within its pores the cleaning will not be abrasion free. This happens with some filled plastics, wood, plaster and similar friable substances.
     
  • If the solid dry ice particles find it difficult to penetrate the surface layer, cleaning will be very slow, e.g. enamels, sealants, etc.
     
  • Dry ice cleaning can be much slower than an abrasive process and cannot create any specific surface finish standard, e.g. rust will be removed, but the underlying steel surface will remain pitted.
     
  • The process is noisy and it is difficult to collect the small amount of debris created by the material removed.
